PAVING- BLOCK.

SPECIFICATION forming part of Letters Patent No. 364,928, da e n 1 1887,

Application filed September 16, 1886. Serial No. 218,063.

To (LZZ whom it may concern:

Beitknown that I, SARAH M. HOYT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improve ments in Paving-Blocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved paving for sidewalks.

Hitherto in the making of most sidewalks,as well as roadways in which artificial paving compositions are employed, the arched upper surface has been produced by giving to the earth or composition or material constituting the roadbcd an arched surface. The result of such a construction has generally been that whenever one part of the road-bed settles or is upheaved a corresponding disturbance of the paving has been produced, causing depressions or protuberances in the upper surface, rendering such surface uneven, and providing receptacles for standing water, render ing travel unpleasant, and producing decomposition and destruction of the paving material.

The object of my invention is to remedy this difficulty; and to this end it consists of a readymade or molded block, of any suitable material ,with an upper surface which tapers gradually from the center to the ends.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a section of sidewalk constructed in accordance with my invention, and Fig. 2 a detail.

In the drawings, A represents a section of my paving material, which may be made of cement and sand run in a mold and allowed to stand and harden, or be made of clay and (N0 model.)

baked, or of any suitable composition made in a similar manner, and which section, in length, is designed to be the full width of the side walk, (preferably six feet-,) and may be from six to twelve inches wide. It is to be molded with a crowned upper surface, which curves gradually from the center to the ends. The under surface may be arched, as shown, to save material; but this is no part of my invention. The road-bed is first leveled, and then the pavement laid in sections, as shown in Fig. 1, and, if desired, they may be secured by curbs on either or both sides.

By the use of my invention it is not esseir tial that the entire road-bed should be perfectly level, as when the under surface of the section is made arching,as shown at B, earth or other material can be packed therein; but, as already indicated, the under surface of each section of my pavement can be made level.

The horizontal dotted line C in Fig. 1 serves to show the relative curvature of the upper surface.

By my improvement sidewalk-builders are furnished with material which can be kept in stock and ready and capable of being laid at any season.

I am aware that arched bricks for building purposes are old; but

WVhat I claim is A pai ing-block such as A, having a length equal to the width of the walk to be covered, and provided with 'a crowned upper surface which tapers slightly toward the ends of the block, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

SARAH M. HOYT.
